Pinworms don't bother the nose - but hookworms, threadworms and whipworms do. They are all species of roundworms.
Their eggs travel in the blood and will deposit themselves into the lungs where they incubate. Once hatched - the tiny larve travel back into the intestines in phelm. Sometimes a few will crawl into the sinus cavaties.
Pinworms lay their eggs on the outside of the anus - and on underwear and bedclothing - they do not travel further up into the body. This is why I think you have a different species of roundworm.
